This is a simple example of presenting a way to have django and node.js communicating for the needs of an application.
Assuming django packages & nodejs have been installed, run django by typing:
(venv) $ python manage.py runserver 0.0.0.0:8000
Run node.js server by typing:
npm start
NOTE: make sure you are on the correct directories.
Finally open several tabs on your favorite browser to visit landing page and see it in action.
